dt-bindings: net: Add UltraRISC DP1000 GMAC

Browse source

The DP1000 integrates a Synopsys DesignWare GMAC from the 5.20 series with
one MMIO register range, one clock and one interrupt.

It also provides fixed TX and RX RGMII clock delays that cannot be
disabled. Board connections must therefore not add either delay in PCB
traces, making "rgmii-id" the only supported phy-mode.
